ABSTRACT:
A predictive coding device has an input terminal through which a sampled value is input, a predicting circuit for outputting a predicted value for the sampled value which has been input through the input terminal, and a look-up table arranged to receive, as a readout address, the sampled value input through the input terminal and the predicted value and then to output a predictive coded value. On the basis of the input sampled value and the predicted value, the predictive coding device determines the readout address for the look-up table which stores a table providing the predictive coded value.
